Specification of Letters Patent.

Patented Dec. 31, 1918.

Application filed June 16, 1917. Serial No. 175,051.

To all whom t may concern.'

Be it known that I, THOMAS J. SHE-EHAN, a citizen of the' United States, residing .at the city of St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Refrigerating Apparatus, of which the following is a specification.

Water at atmospheric temperature or at a temperature of water in water mains is 1n warm weather not satisfying to quench the thirst, while ice water (by which is meant water derived from the melting of ice or water that has come into immediate contact with ice) is detrimental to the health, because of being too intensely cold or on account of impurities in the ice. The object of this invention is to supply water that is indirectly cooled or refrigerated and, more particularly, to provide apparatus for this purpose that is suitable for underground installation in factories, for street fountains, and in other locations where considerable quantities of refrigerated water will be consumed.

In the accompanying drawings forming part of this specification and in which like numbers of reference denote like parts wherever they occur,

Figure 1 is a sectional view showing the interior in elevation with blocks of ice for refrigerating purposes;

Fig. 2 is a sectional view taken at a right angle to the sectional line of Fig. 1 and showing the interior in elevation with part of the interior tank broken away; and

Fig. 3 is a top plan view.

The non-absorbent or non-porous container Imade o-f vitreous ware or other suitable material having the qualities stated is set in a hole in the ground with its lip 2 approaching closely to the surface of the ground, but surfaced and protected with waterproof concrete 3. The said container 1 is provided with the bottom 4 and the floor 5, between which is a Space filled with waterproof concrete 6. The floor 5 and bottom 4 are made of material similar to that composing the container l. The said container 1 is closed at the top by a metal cap 7, the downwardly-depending iiange 8 of which rests upon the metal plate 9 having therethrough an opening normally closed by the lid 10, hinged at 11 and provided with the lifting handle 12. The said hole is in aline- Inent with a similar hole in the cap 7, which latter hole is closed by the cap 13, having the lifting handle 14 and the flanges 15 and 16,

the latter of which rests upon the edge surrounding the hole in cap 7 The said lids and the openings closed thereby are provided for access to the interior of container 1, for the purpose, for instance, of putting blocks of 'ice 17 therein or for any other needful purpose.

A cooling tank 18 is located within the said container 1, and is supported from the floor thereof by the flanged leg 19 and braced from the sides thereof by pipes 20, one of which connects with the water main 21, and is pro-vided with the nipple 22, and is further braced by the pipe 23, and a pipe 23 which connects with the cross 24 that leads to pipe 24EL that leads out through an opening in the wall of container 1 to an overflow drain, as hereinafter described. Pipes 20 and 24a and pipe 23 are located in tapped openings 24 through the walls of the container 1 and tank 18, and are securely fastened therein with lock-nuts: 25 and gaskets 26. r1`he pipes 20 and 24a and the tank 18 may, if desired, be made of galvanized iron or other Suitable material. The gaskets 26 are preferably waterproof.

Studs 27, together with pipes 20 and 28 and pipe 23 and the top of tank 18, form adequate supports for ice that may be introduced into container 1 to cool the liquid in tank 18.

Pipe 28 leads from an opening in tank 18 to a fountain or other fixture or, in case of need, might serve as a main leading to various branches communicating with a plurality of fountains, faucets, or the like.

The container 1 is filled with ice, and the drippings therefrom cover the tank 18 and the branches and chill the water that they contain that enters from the main 21, and when the container 1 is filled with water from the melting of the ice, the same automatically is emptied through the automatic overiow pipe 29 containing the valve-stem 30 adjustable by the hand-wheel 31 and supported by brackets 32. The overflow from pipe 29 leads through the above-mentioned cross to the overflow pipe 24a, which carries the overiow liquid to the drain.

Vhen it is desired to clean the container 1, all the water will be allowed to flow out through the opening 33 upon the opening of the valve 34 by turning the hand-wheel 31, which by means of the stem 30 opens or closes the said valve, and when opened the liquid runs through the drain pipe 35.

The tank 18 is cleaned by opening the valve 36 by applying a wrench to the end 37 which actuates the stem 38. Opening the said valve allows the contents of tank 18 to drain into the container 1, which in turn is cleaned as hereinabove described.

It will be observed that the water from the main 21 enters through the nipple 22 at a point relatively near the top of the tank 18 and above the normal water line 39, such water being relatively warm and sinking to the bottom of tank 18 as and when the same becomes chilled, cold water being heavier than warmer water. Thus the water supply to the drinking fountain, faucet, or

' the like through pipe 28 is that which is the coldest in tank 18, being drawn from its bottom. The entrance being near the top of the tank 18 as well as under the pressure from the main, gives the water a head when le same is drawn through the faucet or the Bosses 26a are formed upon the interior and exterior of the walls of the container 1 and tank 18 at the places Where pipes, etc., are capped therethrough, and in the case of the bosses on containerl 1 are preferably formed integral therewith. The shape of the said bosses in coperation with the gaskets 26 makes a particularly tight water joint.

Having thus described this invention, I hereby reserve the benefit of all changes in form, arrangement, order, or use of parts, as it is evident that many minor changes may be made therein ,without departing from the spirit of this invention.

I claim:

1. In a device of the character described, a container adapted to be sunk in the ground, with the upper end flush with the surface thereof, an outwardly and upwardly turned flange carried by the upper end of said container, means for closing said container, means for preventing the seepage of surface water thereinto, a tank placed concentrically within said container, an induction pipe leading to said tank, and an eduction pipe leading from said tank.

2. In a device of the character described, a container adapted to be sunk in the ground with its upper end flush with the surface thereof, an outwardly and upwardly turned flange carried by said container, means for closing said container, said means der of said flange, a cap having an aperture therethrough and superimposed upon and spaced from said plate and seated thereon, a lid hingedly related to said plate, a closure removably related to said cap, said apertures registering with each other, a tank placed concentrically within said container, a conduit leading from the exterior of said container into said tank, and a conduit leading from said tank to the exterior of said container.

4. In a device of the character described,

a container adapted to be sunk in the ground with its upper end approximately flush with the surface thereof, a tank carried concentrically within said container and spaced from the sides and top and bottom thereof, an induction pipe leading through said container and into said tank, an eduction pipe leading from said tank and extending through the outer wall of said container, and studs carried at right angles to the outer wall of said tank with the outer ends spaced from the inner walls of said container, said studs and said pipes being so placed as to form a support intermediate the top and bottom of said container for blocks of ice.

5. In a device of the character described, a container adapted to hold water, a tank carried within said container and adapted to hold a liquid, an induction pipe leading through said container and into said tank, and an eduction pipe leading from said tank through the outer wall of said container, drain pipes for draining said container and said tank, valves related to said pipes and operable from the interior and adjacent the top of said container.

In testimony whereof I hereunto affix myy signature. Y
